  bibo_abstract:
  - 'JWST’s “little red dots” (LRDs) are increasingly interpreted as active galactic
    nuclei (AGN) obscured by dense thermalized gas rather than dust as evidenced by
    their X-ray weakness, blackbody-like continua, and Balmer line profiles. Key questions
    are how LRDs connect to standard UV-luminous AGN, whether transitional phases
    exist, and whether they are observable. We present the “X-ray dot” (XRD), a compact
    source at z = 3.28 observed by the NIRSpec Wide Guaranteed Time Observation survey.
    The XRD exhibits LRD hallmarks: a blackbody-like (Teff ≃ 6400 K) red continuum,
    a faint but blue rest-UV excess, falling mid-IR emission, and broad Balmer lines
    (FWHM ∼ 2700–3200 km s−1). Unlike LRDs, however, it is remarkably X-ray luminous
    (L2−10 keV = 1044.18 erg s−1) and has a continuum inflection that is blueward
    of the Balmer limit. We find that the red rest-optical and blue mid-IR continuum
    cannot be reproduced by standard dust-attenuated AGN models without invoking extremely
    steep extinction curves, nor can the weak mid-IR emission be reconciled with well-established
    X-ray–torus scaling relations. We therefore consider an alternative scenario:
    the XRD may be an LRD in transition, where the gas envelope dominates the optical
    continuum but optically thin sight lines allow X-rays to escape. The XRD may thus
    provide a physical link between LRDs and standard AGN, offering direct evidence
    that LRDs are powered by supermassive black holes and providing insight into their
    accretion properties.@eng'
